Chapter 1. Installation
1.7.2b Remote-Mounted Enclosure
For a remote mounted enclosure, refer to the wiring diagram in Figure 10 on page 25 and the remote transducer wiring
in Figure 12 on page 27, and complete the following steps:
WARNING! Before connecting the transducers, take them to a safe area and discharge any static buildup by
shorting the center conductor of the transducer cables to the metal shield on the cable
connector.
1. Using the pair of coaxial cables with BNC to BNC connectors supplied by the factory (or equivalent cables),
connect both CH1 transducers to the preamplifier.
CAUTION! As part of maintaining the FM/CSA environmental rating (TYPE 4) on the remote preamplifier,
thread sealant is required on all conduit entries.
2. If an optional lightning protector is being installed, connect it to the preamplifier as shown.
3. Using the supplied coaxial cables with BNC to flying lead connectors (or equivalent cables), route the cables
through one of the conduit holes in the electronics enclosure and connect the preamplifier to terminal block J3.
Secure the cable clamp.
Note: The RED cable leads are the SIG(+) leads and the BLACK cable leads are the RTN(-) leads.
!ATTENTION EUROPEAN CUSTOMERS!
To meet CE Mark requirements, all cables must be installed as described in Appendix A,
CE Mark Compliance.
4. For a 2-Channel XGM868i, repeat steps 3-5 to connect the
CH2 transducers to terminal block J4 in the electronics
enclosure. It is not required that both channels of a 2-Channel unit be connected.
5. If wiring of the unit has been completed, reinstall the rear cover on the enclosure and tighten the set screw.
Note: A channel must be activated before it can begin taking measurements. See Chapter 2, Initial Setup, for
instructions.
Proceed to the next section to continue the initial wiring of the unit.
